a water layer in the receiving flask, remove it with a transfer pipet. Dry the organic layer over
anhydrous sodium sulfate and decant or pipet the product into a clean, dry sample bottle (with a

product. Perform the unsaturation test described below.
Test for Unsaturation (bromination):
Add approximately 20 drops of methylene chloride to three small test tubes. Add 2 drops of the
bromine test reagent (2% Br2 in CH2Cl2) to each test tube with mixing. Immediately add 2 drops
